Religion significantly influences the preservation and proliferation of cultures, which are often explicitly included in the goals of religious existence. Religion in the modern world holds significant potential to impact consumer behavior. Additionally, commercial religious products have increasingly become a source of comfort for individuals experiencing feelings of emptiness. This study applies the concept of pleasure design to a theoretical framework for religious souvenirs of online design store and students' works in Taiwan to understand its influence on consumer preferences. It hypothesizes that the application of pleasure design to religious products enhances the quality of religious beliefs and associations with religious cultures. The results highlight the feasibility of a pleasure design assessment scale for religious products. Further, pleasure design facilitates in-depth explorations of physiological and ideological pleasure that facilitate feelings of peace, happiness, and fun, which in turn promote purchase intentions. The key influencing factors include patterns, model design, and color configuration. An eye-tracking experiment reveals that products with greater detail and more text offer more fixation points. Thus, courses that teach product design and execution as well as the analysis of key design characteristics will help students to not only smoothly transition into the field but also apply the design process to commercial products.
